RICHARD H. THOMAS, OF CHICAGO, ILLINOIS.

AIR PURIFYING AND-COOL|NG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 700,858, dated May 27, 1902.

Application led April 18, 1901. Serial No. 56,507'. (No model.)

To a/ZZ whom, it nuty concern:

Be it known that 1, RICHARD H. THOMAS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Air Purifying and Cooling Apparatus, of which the following is a specification. l

This invention relates to air purifying and cooling apparatus; and it has for its object to provide a construction by the use of which the air may be first washed of its impurities and then dried, further objects and ad vantages relating to the details of construction, which will be apparent from the following description.

In the drawings forming a portion of this specification, and in which like nu merals ofVY reference indicate similar parts in the several views, Figure 1 is a vertical sectional view taken through an air-chute and showing the arrangement of the washing and drying apparatus therein. Fig. 2 is a section taken at right angles to the section of Fig. 1 andrshowing the Washing and drying apparatus in' plan.

Fig. 3 is a View similar to Fig. 2 and showing the substitution of fabric for the cables.

Referring now to the drawings, there is shown a chamber 5, having the air-chute sections 6 and 7 connected at opposite sides thereof, so that the chamber is a'continuation or portion of the chute, the lower portionA of the chamber being extended below the' chute-sections referred to and forming a tank S to receive water to be used in washing the air.

Covering the openings in the sides of the chamber 5 with which the chute-sections 'communicate are screens 9 and 10, and within the chamber and between these screens is the Vertically above the roller 11 is a roller 17,

close to the top of the chamber 5, and in the rear of the roller 17 are other rollers 18, 19, 20, and 21, and in staggered relation to these last-named roilers and at the bottom of the so that as the roller 1l is rotated the cables will be caused to travel upwardly and downwardly through the chamber 5 and back through the water in the tank, the water serving to wash the cables and to wet them, vso that dust particles will adhere. Thus the first 4vertical portions of the cables are wet, and

air coming through the adjacent screen comes in contact with these wet cables, and the solid particles in the air strike the cables and are taken up by the water thereon. The second, third, and fourth sections of the cables are also wet and have the same action to remove impurities; but asthe cables pass around the roller 24 they pass between a drying-roller or wringer 28, which acts to compress the cables and to squeeze the water therefrom, and as the rollers 22, 23, and 24 do not carry the cables below the water-level of the tank they act to take up the moisture that maybe blown by the air from the wet cables, and the air as it iinally passes through the back screen is dry and free from impurities of a solid nature. The cables in their passage through the tank are washed.

In Fig. 3 of the drawings there is shown a construction wherein a fabric belt is substituted forvthe cables, the operation being practically the same and the fabric being sufficiently open to permit the air to blow through.

In practice other modifications may be made and any suitable materials and proportions may be used for the various parts without departing from the spirit of the'invention.

What is claimed .is-

1. An air washing and drying apparatus IOO comprising a chamber having a tank communicatingl therewith and adapted to hold a liquid, rollers disposed to dip into the tank, rollers disposed at the top of the chamber, rollers disposed betweenthe first and second series of rollers, a Wringer coacting with one of the rollers, an absorbent material extending transversely throughout the Width of the chamber and passed over the rollers to move in planes at angles to the liquid-level of the tank, and air-chutes disposed to convey air to and from the chamber for passage through the absorbent material, whereby the air will be first washed and then dried.

2. A device for Washing and drying air comprising a chamber having a liquid-holding tank, and absorbent material extending throughout the width of the chamber, guiderollers disposed to direct'the material first through the tank and then backwardly and forwardly thereabove, and a Wringer coactng n with one of the rollers, said chamber having air inlet and outlet openings to permit of pas- -sage of air to through and from the absorb RICHARD II. THOMAS.
